Arctic Heart (French: Le Secret des banquises) is a 2016 French romantic comedy film written and directed by Marie Madinier.

Christophine, a shy and young PhD student who is secretly in love with Quignard, decides to inject herself with the penguin genome, in an attempt to advance the professor's research and to get closer to him.

The results finally lead him to his goals, and he is selected to win the Nobel Prize, but Christophine realises that her body is changing and reacting to the experiments, and she decides to stay alone, closing herself to everything.

When the professor finds out, he tries every possible way to save her but he has no option left other than sending her to Antarctica to live with penguins.

The professor then injects himself with the same drug that Christophine took and goes and lives with her in Antarctica, after having grasped his feelings for her.
